8.4. MANUAL CALIBRATION WITH ZERO/SPAN VALVES
Zero and Span calibrations using the Zero/Span Valve option are similar to that described in Section 7.2, except
that:
Zero air and span gas is supplied to the analyzer through the zero gas and span gas inlets rather than
through the sample inlet.
The zero and cal operations are initiated directly and independently with dedicated keys (CALZ & CALS)
STEP ONE: Connect the sources of zero air and span gas to the respective ports on the rear panel (refer to
Figure 3-1) as shown below.

STEP TWO: Set the expected SO

span gas value:
This sequence causes the
analyzer to prompt for the
expected SO
2
span
concentration.
M-P CAL SO2 SPAN CONC: 450.0 Conc
0 0 0 4 5 .0 ENTR EXIT
M-P CAL RANGE = 500.000 PPB SO2 =XXX.X
< TST TST > ZERO CONC EXIT
SAMPLE RANGE = 500.000 PPB SO2 =XXX.X
< TST TST > CAL SETUP
The SO
2
span concentration
values automatically default
to 450.0 Conc.
To change this value to the
actual concentration of the
span gas, enter the number
by pressing the key under
each digit until the expected
value appears.
The span gas concentration
should always be 90% of the
selected reporting range
EXAMPLE
Reporting range = 800 ppb
Span gas conc.= 720 ppb
EXIT ignores the new setting
and returns to the previous
display.
ENTR accepts the new setting
and returns to the
previous display..
